Monologous has a more "ordered" and "clean" look than most of the other dialogue fonts on this site. Depending on your tastes, this is either a good or bad thing. I personally like it.
However, when lettering, you might notice that the "capital" letters of the font are actually lower than the small ones. It's a little off-putting. But once you learn to letter like an actual comic book letterer, WITHOUT using caps at the beginning of sentences, it is an attractive font. Still unintuitive though.
